PG&E Achieves 400% Increase in Posted Integration Capacity After Data Refresh with GridUnity Software

“PG&E worked with platform-as-a-service and cloud analytics company GridUnity to conduct a system-wide refresh intended to improve the accuracy of results and better operationalize the ICA data by re-analyzing all valid circuits. The PG&E engineering team utilized GridUnity’s Grid Model Management (GMM) software to drive automated analyses and management-by-exception workflows to ensure completeness of model data and resolve power flow issues in a methodical, collaborative, and consistently repeatable process. As a part of this effort, GridUnity’s GMM software capabilities were expanded and improvements were made to 1) PG&E’s forecasting software, 2) PG&E’s distribution power flow software and ICA algorithm, and 3) PG&E’s Electric Distribution GIS.

As of April 2020, PG&E has completed the refresh, with the result being a nearly 400 percent increase in posted integration capacity.

Before the refresh, the system average of distribution line section integration capacity was 126 kilowatts (kW). After the refresh, the system average of line section capacity increased to 500 kW.”
